I'm just a bit confused as to why Bungie and 343 often use British versions of some words. 'The Pillar of Autumn' and the Halo 4 song 'This Armour' come to mind. Is it just preference, because admittedly Pillar of Autumn' carries a bit more granduer than Pillar of Fall (I'm English by the way, just wondering why American companies would use these versions of the words).
